When building a vector via tint::writer::AppendVector, and the
vector argument is already a vector constructor, expand that
vector constructor into its components only when those components
are all scalars. This avoids a type breakage which can occur with cases
like this:
vector argument is:
vec2<i32>(vec2<u32>(0u,1u))
scalar argument is:
2
Before this fix, the result was:
vec2<i32>(0u, 1u, 2);
But should be this instead:
vec3<i32>(vec2<u32>(0u,1u),2)
This was noticed in SPIR-V writer output when forming a coordinate
vector from a an unsigned WGSL coordinate vector with a signed array
vector.
Fixed: tint:1048

This adds SPIR-V assembly and WGSL tests derived from VK-GL-CTS commit
571256871c2e2f03995373e1e4a02958d8cd8cf5. The following procedure was
followed:
- Those .amber files in VK-GL-CTS wholly owned by Google were
identified
- All GLSL and SPIR-V shaders were extracted from the Amber files and
converted into SPIR-V binaries
- The compact-ids pass of spirv-opt was applied to each binary
- Duplicate binaries were removed
- spirv-opt -O was used to obtain an optimized version of each remaining
binary, with duplicates discarded
- Binaries that failed validation using spirv-val with target
environment SPIR-V 1.3 were discarded
- Those binaries that tint could not successfully convert into WGSL were
put aside for further investigation
- SPIR-V assembly versions of the remaining binaries are included in
this CL
- test-runner with -generate-expected and -generate-skip was used to
generate expected .spvasm, .msl, .hlsl and .wgsl outputs for these
SPIR-V assembly tests
- Each successfully-generated .expected.wgsl is included in this CL
again, as a WGLSL test
- test-runner with -generate-expected and -generate-skip was used again,
to generate expected outputs for these WGSL tests
